INE R&S ATC020- Rapid Spanning-Tree Protocol (RSTP), Rapid-PVST

Rapid Spanning-Tree Protocol

• Rapid convergence based on sync process
• Enabled through…
– spanning-tree mode mst
– spanning-tree mode rapid-pvst
• Sync process only occurs on point-to-point non-edge ports
– Implies link-type must be accurate
– spanning-tree link-type [point-to-point|shared]
– spanning-tree portfast

========================================
P2P Full duplex
Non-Edge

PC連接上SW後, 很慢, 並且當Root Port若是改變, PC會無法連線30s
SW會送Send Proposal Out, PC若沒回應(LIS,LRN,FWD共30s)
解決方式: 準確的設定spanning-tree portfast於SW Port上.....P2P Edge....
